中国地震仪器烈度滤波器的设计
|
摘要
在充分理解吸收日本JMA滤波器设计特点的基础上,由单自由度动力平衡方程入手,利用两高通滤波器相减可得到带通滤波器的方法,通过调整平衡方程参数进行了滤波器的设计,通过对日本滤波器进行模拟,验证了方法的可行性,并且通过双向递归的方法解决了时域递归方程中的相位畸变问题,最终完成中国仪器烈度滤波器的设计。
This paper described the filter design on the basis of fully understanding and absorbing the design features of the Japanese filter of JMA.Starting from dynamic equilibrium equation for single-degree-of-freedom,the band-pass filter was obtained by subtracting two high-pass filters and adjusting the parameters of the equilibrium equation.The feasibility of the proposed method was validated through simulating the JMA filter,and the phase distortion problem in time domain recursive equation was resolved using the bidirectional recursion method.The design of Chinese instrumental seismic intensity was thus completed.
